My wife and I have been married for over 10 years. In the beginning, sex was great but it fizzled out after a couple years. Now, our sex life has become very vanilla. I've heard her speaking to her friends about black men, penis size (i think she's an undercover size queen) and being completely dominated. Overhearing this turned me on like nothing else and I now fantasize about her having unrestrained pleasure with someone else. I have spoken to her about it but she keeps being coy, to not hurt my feelings i guess. Any advice on how to get her to open up and live out this fantasy?
